The ISAT program is developing technologies that enable the deployment of extremely large electronically scanning antennas in space, and the metrology and calibration technologies necessary for coherent beamforming from such large antennas. These huge antennas enable the revolutionary performance required to conduct tactical sensing from space, including missions like continuous reliable tracking of surface targets.[3]
